i have a 92 ls and when i start my engine it runs for about 2 seconds and then stall. I have to wait something like half an hour before i can start it again and it does the same thing. Anyone have had this problem before ? What can be the cause of this ? How can i know if the gas pump is damaged ?

thanks

 

Main relay maybe?

 

I dont know if this helps but when you turn the key to #2 do you hear the fuel pump?

 

when i turn the key to the ON position i don't hear anything
